TECHNICAL FIELD OF THE INVENTION

Generally, the present invention is related to endoluminal surgicaldevices, methods, device, and drug delivery. More particularly, thedevices and methods provide for endoluminal gastric restriction,endoluminal gastric tissue reconfiguration, endoluminal drug delivery,endoluminal device delivery, and the like.

BACKGROUND OF THE FIELD OF THE INVENTION

Laparoscopic surgery has greatly reduced the size and scope of incisionsmade in a patient and resulted in reduced morbidity and mortality rates.However, even with the reductions in the size and scope of incisions asa result of laparoscopic surgery, complications in and during surgicalprocedures remain. A technique that is developing to further reducesurgical complications is to work through an endoluminal access port.One endoluminal access port is the mouth and this access port can give asurgeon access to a patient's esophagus and stomach.

Stomach tissue often needs surgical treatment to treat fistulas and toclose transgastric incisions to stop stomach fluids from leaking fromthe stomach to surrounding tissue and to stop infectious matter fromspreading from or to the stomach tissue. Other stomach treatmentsinclude stomach reduction procedures for obese patients. Traditionally,physicians have been placing devices such as the Lap Band® on theexternal surface of the gastric wall to create a restricted stomachcapacity. Another traditional procedure for stomach reduction includes alaparoscopic procedure in which surgeons protrude into the stomach fromthe exterior of the patient and staple the stomach into a smallervolume. This restriction creates a pouch inside the stomach which fillsquickly when food is ingested and assists in generating a sensation ofbeing full. However, these procedures have drawbacks such ascomplications from port punctures of the stomach, large incisions,substantial recovery time, expense, lost productive work time,infection, and the like.

However, the incision required by the current surgical proceduresinclude a morbidity and mortality rate that can be reduced by reducingor eliminating the need for an incision by approaching the surgical sitethrough endoluminal procedures.

Referring now to FIGS. 10-12C, a plication that forms an open pocket orbiologic tube is shown. In FIG. 10, an end effecter 200 has a first arm1002, a second arm 1004, and a tissue retractor 1014 and is used to forma tissue plication 1006, as described herein. Plication 1006 is formedby grasping tissue with retractor 1014 and manipulating first arm 1002and second arm 1004 together such that needle 1008 pierces the tissue.Suture 1012 is associated with needle 1008 such that suture 1012 ispierced through tissue with needle 1008. After piercing the tissue withneedle 1008, the tissue is retained on needle 1008. Referring now toFIG. 11, retractor 1014 is used a second time to grasp a second portionof tissue such that the tissue can be positioned with respect to firstarm 1002, second arm 1004, and needle 1008 and be pierced with needle1008 to form second plication 1102. By forming two adjacent plications1006 and 1102, an open pocket 1104 is formed. In some embodiments, animplant 1106 is housed in open pocket 1104.

In some embodiments, end effecter 200 can have multiple retractors 1014such that the retractor does not have to be removed from the tissueafter forming a first plication in order to form a second plication. Inother words, a first retractor 1014 can grasp tissue and form a firstplication while a second retractor grasps other tissue and forms asecond plication. Next, the two plications can be anchored together suchthat an open pocket 1104 is formed therebetween. In yet otherembodiments, tissue graspers are introduced into the surgical sitepercutaneously for grasping tissue and manipulating it into adjacentplications that form the tube or open pocket 1104. In some embodiments,the tissue graspers pull tissue around the shaft 102 of the surgicaldevice and position the tissue for implantation of the anchor object.Next, an anchor object is implanted to fasten the plications around theshaft of the surgical device. After the desired number of plications arefixed around the shaft of the surgical device, the end effecter 200 isstraightened such as to be axially aligned with shaft 102 and the shaft102 and end effecter 200 are removed through the open pocket 1104 of thetissue plications, leaving behind open pocket 1104, or as shown in FIGS.12B and 12C artificial tissue tube 1250.

According to some embodiments, as shown in FIG. 12A, tissue 1220 thatforms pocket 1104 between plications 1006 and 1102 may be tissue thatrequires treatment or can be used for locating a treatment. According tosuch embodiments, implant 1106 positioned in pocket 1104 is configuredto treat tissue 1220 or otherwise provide treatment to surroundingareas. In other embodiments, tissue 1220 can be removed following thedouble plication procedure described with respect to FIGS. 10-12A. Inother embodiments, tissue 1220 may dissolve or resorb following thedouble plication procedure.

In other embodiments, multiple double plication procedures, such as thedouble plication procedure described with respect to FIGS. 10-12C can beperformed on the same tissue, in the same organ, or the like. In someembodiments, as shown in FIGS. 12B-12C axially aligned double plications1240, 1242, 1244, and 1246 can be positioned adjacent to each other suchthat each open pocket 1104, formed between the plications 1006 and 1102,is generally aligned and forms an artificial biological tube 1250. Insome embodiments, artificial biological tube 1250 is formed by drawingeach double plication together. In some embodiments, each plication1240, 1242, 1244, and/or 1246 can be drawn together using surgical glue,suture material, surgical wire, staples, scoring the tissue such thatthe tissue reforms together, combinations thereof, or the like.

In some embodiments, vertically aligned double plications 1240, 1242,and 1244 are positioned, beginning at or distally near thegastro-esophageal-junction (GEJ) 1252 and extend into the stomach,thereby forming an artificial GEJ or gastric tube 1250. In someembodiments, when the artificial gastric tube is flaccid, i.e., empty,the artificial gastric tube acts as a gastric flap or valve forprotecting the esophagus from gastric fluids. Thus, the formation ofsuch an artificial gastric tube can be a treatment for gastro-esophagealreflux disorder (GERD). In other embodiments, the formation of anartificial gastric tube can be a technique for gastric reconstruction orreduction surgery. According to such embodiments, the formation of suchan artificial gastric tube effectively reduces the volume of the stomachof a patient, and thereby, stimulates the stomach into providing a senseof satiety with consumption of a smaller amount of food. According tosome embodiments, between 1 and about 10 plications are positionedadjacent each other to form artificial tube 1250. In other embodiments,between 1 and about 8 plications are positioned adjacent each other toform artificial tube 1250. In yet other embodiments, between 1 and about5 plications are positioned adjacent each other to form artificial tube1250. In yet other embodiments, between 1 and about 3 plications arepositioned adjacent each other to form artificial tube 1250.
